I came across a very nice article(tutorial?) on halftones: [link]

It actually covers the subject a bit better than an old kodak book of mine and it's worth taking a look at if you're interested in binary images and black and white comics. There's a nice little section on photocopy experiments that almost seems like it had comickers in mind.

Otherwise, would anyone be interested in any of my tone patterns? They're not graphic ready like most halftone patterns you'll find on-line, but they're designed for process like the example of the contact sheet in the article and have a 10 - 90% range. If anyone wanted graphic ready sets, I could easily do that too though.
